They have already, Geremia. They have been slowly invading, electronically, concretely, and politically, since the late 1980's. The only thing that China hasn't done is invade militarily. Why should they? Unnecessary, especially now. No need to waste military resources when you can accomplish the same through willing collaboration with traitors, liars, and cheats in Big Tech.
This.
There are more effective ways to conquer than by the sword. If they invaded with an army, tanks, planes, etc. then the Left and Right MIGHT (just might) unique against a common enemy.
But as it stands now, the Democratic Party is basically taken over by Communists, is pushing Communism, and the so-called "president elect" is completely in China's pocket. What more could they ask for, seriously?
